René Chudeau
René Chudeau (21 August 1864, in Angers – 1921) was a French geologist. Formerly an instructor at the University of Besançon, from 1905 to 1914 he conducted a series of geological surveys in the Sahara (later day nations of Mali, Mauritania and Niger). His interests included Quaternary deposits, the formation of sand dunes, processes of aeolian erosion, et al. In the Taoudeni basin, he investigated ancient volcanoes, and south of Agadez, he found the presence of dinosaur bones. In the Zinder region, he made a discovery of Lower Cretaceous rocks being overlain by Upper Cretaceous successions. His geological collections are housed at the Muséum national d'histoire naturelle in Paris. The botanical species ''Pennisetum chudeaui'' Trab. Maire is named in his honor.

Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethnography
Ethnography (from Greek ''ethnos'' "folk, people, nation" and ''grapho'' "I write") is a branch of anthropology and the systematic study of individual cultures. Ethnography explores cultural phenomena from the point of view of the subject of the study. Ethnography is also a type of social research that involves examining the behavior of the participants in a given social situation and understanding the group members' own interpretation of such behavior. Ethnography in simple terms is a type of qualitative research where a person puts themselves in a specific community or organization in attempt to learn about their cultures from a first person point-of-view. As a form of inquiry, ethnography relies heavily on participant observation—on the researcher participating in the setting or with the people being studied, at least in some marginal role, and seeking to document, in detail, patterns of social interaction and the perspectives of participants, and to understand these i ...
